On the Legal Consequences of Brexit (on the example of personal data protection)

The article explores the legal consequences of the UK's withdrawal from the European Union. The scope of personal data protection was taken as an example. The purpose of the article is to study and analyze the legal aspects of the termination of the UK's membership in the European Union, its impact on the cross-border transfer of personal data between the parties, as well as the development of legal regulation in this area. The article shows that, despite the signing of the Withdrawal Agreement, as well as the Trade and Cooperation Agreement, there is a complication of legal regulation, as well as the emergence of potential contradictions and threats to the interests of interested parties. The sphere of personal data protection clearly demonstrates that despite the desire for the sovereignization of legal regulation on the part of the UK, its legal system remains dependent on the legal order of the European Union. The UK's national regulation on personal data will be under constant monitoring by the competent EU authorities, which indirectly confirms the failure to achieve the goals of the full return of the UK's delegated sovereign powers. It is concluded that the EU Court of Justice still retains its jurisdiction over the United Kingdom, in particular, in connection with possibility to challenge decisions on adequacy, as well as through the adoption of its own practice on issues related to personal data protection.
